With the root of Taoism in China and its popularity among the people, the health-preserving culture of Midao has gradually formed a set of unique ideological principles in its long history, which fully embodies the background of traditional culture in China. From the Taoist ancestor Laozi's Tao Te Ching and China's classic medical work Huangdi Neijing, it can be seen that China's traditional philosophy attaches great importance to nature as an ordinary whole, and puts forward the ideas of correspondence between man and nature, induction between man and nature and so on. It is believed that everything in the world does not exist in isolation, but all interact, influence, relate and depend on each other. Therefore, this principle has been fully reflected in Taoist health culture.

Midao's health theory advocates that "knowing astronomy from above, geography from below, and personnel from middle can last for a long time". Here, astronomy, geography and personnel are obviously treated as a whole. People are not only natural people, but also social people. People live in nature, but also in the personnel society, and can not do without social groups. There are biological factors, social factors and psychological factors that affect health and disease, which is an objective fact that people have felt since ancient times. Taoist health preservation starts from the viewpoint of "correspondence between man and nature" and "secular desire", and understands and understands human health and diseases from the relationship between man and nature and between man and society. It attaches great importance to the role of natural environment and psychological factors, and runs through all aspects of etiological examination, treatment and health care and prevention. For example, it is emphasized that health care should be "suitable for cold and summer". At the same time, it is considered that the human body itself is an organic whole, that is, a small universe and a small celestial body. The five internal organs of human beings are connected with five bodies, nine orifices, five sounds, five senses, five liquids and five flavors, which constitute the whole human body and five systems. On this basis, according to the exterior-interior relationship of zang-fu organs, they are linked through meridians, thus completing the life activities of human body harmoniously. This unity of form and spirit of Taoism has formed a dialectical materialist view of observing the world and everything in the world, and a holistic view of China's traditional culture based on it. "Su Wenzhi's Theory of Truth" "I want to examine the place of Yin and Yang, and adjust it to make it last for a long time".

Midao's health preserving theory holds that Yin and Yang respectively represent the opposite sides of the human body. Neijing says: "The origin of life lies in Yin and Yang", which shows that the law of human formation, growth and development cannot be separated from Yin and Yang. Under the normal physiological state of human body, the relative balance of yin and yang is maintained. If one party is weak or the other party is overactive, the normal physiological function of the human body will be disordered and a pathological state will appear. Human health, whether it is diet, psychological adjustment, self-exercise or drug action, can not be separated from the purpose of coordinating and balancing Yin and Yang. People's aging is either yin deficiency, yang deficiency or both yin and yang deficiency. Yin deficiency leads to hyperactivity of yang, yang deficiency leads to excess of yin, excess of yin leads to yang disease, and excess of yang leads to yin disease. Therefore, to prevent aging, it is important to reconcile Yin and Yang, make Yin and Pingyang secret and cure the spirit. This shows that Taoist culture rooted in China attaches great importance to the concept of symmetry, and the industry attaches great importance to the philosophical basis of balance. Taoist philosophy has long known the dialectical relationship between motion and static. In Zhouyi, it is proposed that "all movements are normal", and in Lv Chunqiu, it is proposed that "running water does not rot, regardless of the household pivot". The substances in nature are constantly moving and changing. Only exercise can change, and only exercise can produce everything. Taoism believes that the whole process of human life activities, from occurrence, development to extinction, always runs through a series of internal contradictory movements, ups and downs. Neijing puts forward that "high and low occupy each other, rise and fall are related and change each other." Exercise is a natural law and the most basic factor to maintain human health. The law of life movement is the process of metabolism. If there is an obstacle to human movement, it is a disease. Therefore, TCM attaches great importance to the prevention and treatment of diseases with the viewpoint of exercise change. Life lies in exercise, because exercise is the characteristic of life, and every cell of people is moving. Only by persisting in regular exercise can we improve our health, prevent diseases and prolong our life.

In Taoist philosophy, there is even a saying of "governing tranquility". Laozi said: "Quiet is the best in the world" and "quiet but not vulgar"; Cai Qing in the Ming Dynasty said: "The reason why heaven and earth have lasted for a long time is that they are lucky enough not to leak their ears, so the benevolent is at peace." It can be seen that China's Taoist ideology and culture deeply influenced and dominated China's health-preserving theory, which developed into a theory of health-preserving and self-cultivation, and derived many multi-religious and multi-genre health-preserving exercises, qigong (including cohesion and outward expansion) and other exercises from the Taoist health-preserving theory. The "stillness" here is not absolute stillness, but another form of movement. Exercise is absolute, static, relative, dynamic and static, and it is the main purpose of health care. This simple dialectics of Midao is the characteristic and advantage of China's philosophy. The overall dialectical view defined by Taoism embodies this feature of China culture. Taoist health care emphasizes adapting to the time, place and people, and formulates health care programs according to different seasons, regions and personal physique, gender and age. Man is a part of nature and has a close relationship with nature. People should know nature, conform to nature, adapt to nature, and at the same time rise and fall according to the yin and yang of individuals? The situation is adjusted to achieve health and longevity. This fully embodies the principle and flexibility of Taoism, which summarizes this principle as "knowing it is constant and changing".

Taoist health preserving theory emphasizes dialectical treatment. Distinguish symptoms, analyze the causes, nature and development trend, determine the nature of the disease in combination with specific conditions, comprehensively formulate treatment principles, and implement treatment methods as a whole, which is called dialectical treatment. When practicing, we should choose related exercise items according to different age, physique, season and disease nature, and adopt appropriate exercise methods to improve the effect of practice.

Midao health culture is a part of China culture, which highlights the essence of China traditional culture.
